For some Americans, the morning after Election Night has been especially dark.

Social media users took to Twitter and Instagram in the hours following the election results to protest Donald Trump's shocking win over Hillary Clinton with a black box in place of a profile picture. Pegged as #TwitterBlackout, the movement, which is quickly gaining traction online, is a way to "create unity" amidst a seemingly divided nation.

Katy Perry changed her Twitter profile and header image Wednesday, tweeting, "Do not sit still. Do not weep. MOVE. We are not a nation that will let HATE lead us," and later adding, "Fight for what is RIGHT."

The pop singer is one of many celebrities that have spoken out on social media and in person regarding Trump taking the White House, and they haven't shown signs of slowing.

Lady Gaga took her disappointment to the streets early this morning as she stood outside Trump Tower in New York City with a sign that read "Love trumps hate." Miley Cyrus shared her own emotional response to Clinton's loss on Twitter, telling the camera in a video, "Donald Trump, I accept you. And this hurts to say, but I even accept you as the President of the United States, and that's fine... because I think now I want to be hopeful."

Both Barack Obama and Clinton have since spoken publicly about the election results, sharing hope-centric messages with the American people.

Trump's victory was declared around 2:30 a.m. ET, and during his speech he praised Clinton's efforts throughout the election. He said she was owed a "deep debt of gratitude" for all her hard work.
